摘要：Background:
The aim of the present study was assessing the changes in Iranian household food basket. The Households Income and Expenditure Survey (HIES) data of 717,432 of Iranian households from 1991 to 2017 were used in this repeated cross-sectional study.
Methods:
A cross-classified random-effects modeling (CCREM) specifications of hierarchical age-period-cohort (HAPC) in two models, one without controlling for the effects of key individual characteristics, namely socioeconomic status; household size; place; and household head sex, and another one with controlling for the effect of mentioned variables, was used in the present study.
Results:
The present study showed that the equivalent to an adult male daily consumption of “total calorie” (
P value = 0.0001) and “fats, oils, sugars, and sweets” (
P value = 0.0002) had an increasing trend from 1991 to 2004 and a decreasing trend from 2005 to 2017 among Iranian households. The daily consumption of “bread, cereal, rice, and pasta” (
P value = 0.0001) had a decreasing and “fruits” (
P value = 0.0002) had a rising trend during periods. After an increasing trend for the “meat, poultry, fish, eggs, legumes, and nuts” (
P value = 0.0002) and “vegetable” (
P value=<0.0001) by 2004, there was a decreasing trend from 2004 to 2017, but the share of them in the total calorie consumption increased. The “dairy” (
P value = 0.0002) consumption had a decreasing trend in recent years.
Conclusions:
Iranian household food basket, during these years, had significant changes that some of them (increase in the share of the vegetables and fruits in the total calorie intake) are positive and some of them are negative (decrease in the consumption of dairy).
